[PATCH 09/18] perf evsel: Adopt parse_sample method from perf_event

From: Arnaldo Carvalho de Melo
Date: Fri Aug 03 2012 - 10:02:15 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Since we need evsel->{attr.{sample_{id_all,type}},sample_size},
reducing the number of parameters tools have to pass.
